The area of the school computer room is 85 square meters, with 60 cm square tiles on the side. Is 200 pieces enough?

The area of the school computer room is 85 square meters, with 60 cm square tiles on the side. Is 200 pieces enough?

60x60 = 3600 (square centimeter), 85m2 = 850000 (square centimeter), 850000-3600 two 236.1111111 The answer is not enough

The area of the school classroom is 80 square meters, with a side length of 0.6 meters of square tiles, buy 220 is enough?

0.6x0.6 = 0.36 m2, 1 m2 divided by 0.36 M2 = 2.7 pieces of bricks, 2.7 pieces of bricks multiplied by 80 m2 = 216 pieces, it is certainly not enough, because at least 5% - 10% of the loss should be included, so it is better to have more pieces just in case. If the bricks are not purchased in the same batch, it may cause problems of different quality and color difference in the later stage

Cut a piece of rectangular paper with a circumference of 80 cm into three pieces of square paper. How many cm is the circumference of each square paper

Ask vs,
After the rectangular paper is cut into a square, the original width is used to make the side length of the square. Three sides of the square on both sides are the original sides, and two sides of the square in the middle are the original sides
80 (3 + 2 + 3) = 10 (CM)
The perimeter of a square is:
10 × 4 = 40 (CM)

The circumference of a rectangular piece of paper is 80cm, and the ratio of length to width is 5:3. If you cut it into the largest circle, how many square centimeters is the area of the circular piece of paper
We should have formula and strive for strong people·

If the ratio of length to width is 5:3, width = 3 / (5 + 3) * 80 / 2 = 3 / 8 * 40 = 15 cm
Then radius = w / 2 = 15 / 2 cm
And the area of the circle = π R ^ 2 = 225 π / 4 square centimeter

The circumference of a rectangle is 80cm, and the ratio of length to width is 5:3. If you cut it into the largest square, what is the area of the square

80÷2 ÷（5 +3）× 3
= 40÷ 8×3
=15 cm square side length
15 × 15 = 225 square centimeter square area

Use the equation to solve the problem: 1. The perimeter of a square is 60 cm. How many cm are its sides

The perimeter of a square is four times the side length. Let the side length be a, then 4A = 60. The solution is a = 15

When the side length of a square is increased by 1 / 4, the perimeter of the new square is 60 cm. What is the side length of the original square

The side length of the new square is 60 / 4 = 15 cm
The original side length of the square is 15 (1 + 1 / 4) = 12 cm

The circumference of a square is 36 cm, and its side length is______ Cm

36 △ 4 = 9 (CM). A: its side length is 9 cm. So the answer is: 9

For a square, the side length is a centimeter. If the side length is increased by 1 centimeter, then the current perimeter is 12 centimeters. What is a?

From the meaning of the question, (1 + a) × 4 = 12 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 1 + a = 3 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; a = 2; a is 2

If the side length of a square is increased by 1 cm, then the perimeter is now 12 cm. How many cm is the original side length of the square? (equation calculation)

Let the original side length be x cm
（x+1）X4=12
x+1=12÷4
x+1=3
x=3-1
x=2
